What is a U-value and how high should it be?
The U-value or U-factor indicates how much energy or heat passes through a material when there are different temperatures on both sides. The U-value is given with the unit W/m2K (watts per square metre and Kelvin).
The lower it is, the better the insulating performance of a material. Thanks to years of experience in the field of loft ladders, Minka is an expert in high-quality insulation technology. The U-values of our products range between 0.1 and 1.3 W/m2K. With the matching ISO top cover, the values can be reduced even further.
